PLANTS OF CALIFORNIA. 
BY T. S. BRANDEGEE. - 
Isomeris arborea Nutt. The type locality of this capparid is 
San Diego. The original description of its fruit, ‘‘capsule an 
inch or more long 2nd three-fourths of an inch broad,’’ is very 
nearly the description of an orbicular capsule. Some of the 
Desert forms have capsules 7 cm. long including the stipe, and 1 
em. wide, and are long-attenuate at each end. The form of the 
Capsule from the type locality is nearly that of 7. g/lodosa. 
Fagonia Californica Benth. ‘The form that grows in the foot- 
hills of the western side of the Colorado Desert is frutescent, erect, 
and the angles of the stems are scabrous, often as much so as 
those of F. aspera from Chili. On the hills of the Desert, east of 
the Cuyamaca Mountains, grows a form so distinct that it seems 
almost another species, but it probably can be referred to the 
variety Barclayana; it is prostrate on barren ground, the stems 
are slightly angled and not frutescent, the leaves and flowers are 
larger than those of other forms, and the whole plant is thickly 
beset with amber-colored glands. My specimens from Magda- 
lena Bay, the type locality, have broader leaflets than the Cali- 
fornia mountain specimens, the stems are hardly frutescent at 
base and are not scabrous. At San Jose del Cabo the plants are 
pubescent, and in the adjaceut mountains the form is glabrous, 
the leaflets are very narrow and the stipules long and slender. 
nothera cardiophylla Torr. The “Botany of California’’ 
ives as the habitat of this species: ‘‘ Near the Colorado River 
and eastward in Arizona.’’ It grows in the cafions of Carriso 
and Split Mountains of the Colorado Desert.
